If you bought the "Fountain" DVD and you were disappointed at the lack of a commentary track, be patient: Darren Aronofsky is cooking something up.
Aronofsky blogs his displeasure with the DVD process on "The Fountain" by saying "Everything at the studio was a struggle. For instance, they didn’t want to do a commentary track cause they felt it wouldn’t help sales. I didn’t have it in me to fight anymore. Whatever."
But he promises to record a downloadable track that you can play as a traditional commentary track. And he also plans to knock on a few doors at Criterion: "I got a lot of extras in my bag so who know maybe if you all write to criterion they’ll get interested (suggest the fountain as a title: email@example.com).

So there you go, Fountain fans. A piece of good news and a (polite) email to write.
